The combining ability of five male sterile lines -107, 108, A-l, A-65 and A-21, used as females, and the cultivars Chirpan-539, Beli Iskar (No. 800), Natalia (No. 361), the lines No. 5, T-3 (G. hirsutum L.) and the variety Giza-77 (G. barbadense L.), used as males, was studied in 2005-2006. The hybrids obtained were tested for productivity per. plant. The line A-I of the females - MS lines, the cultivar Chirpan-539 and the line Jfe 5 of the males, having positive GC A and high variances of SCA, appeared to be the most suitable for the heterotic breeding. Some crosses differed in high and constant SCA effects. The crosses A-I * Chirpan-539 and A-65 x No. 5, distinguished by the highest SCA effects and the highest productivity per plant, proved to be the most promising.
